It is hard to decide which one I liked more: TID or TMI. The truth is both these series have many many similarities and disappointment. However, I did fall in love with Clary by the end of the series but I just plainly dislike Tessa. I think when it comes to story TMI were much more interesting. Frankly, when I read Clockwork Angel I thought I will never finish the series. The book was torture to me. But Clockwork Prince changed it completely. I actually did enjoy it very much. Unfortunately, the final book in the series was disappointing, I did not like how Cassandra Clare decided to finish it. I just did not. I think I must admit to the fact that TID series for me is on the 'read series but easy forgettable' shelf. In that aspect, TMI series is way more superior. It had a perfect ending, the main thing I missed in this series. It just wasn't what I expected, I guess.
